AI Technical Summary

Benefits of technology

The present invention provides an improved safety system for aircraft during taxiing. The system uses a head tracking device, a processing element, and a full-color head worn display to create a virtual airport scene based on the head position and current aircraft location. This virtual airport scene is then displayed on the full-color head worn display for the pilot to see. The current aircraft location information can be received from various sources such as GPS, inertial navigation, or multi-lateration systems. The technical effect of this invention is to enhance the pilot's situational awareness and provide better safety during surface operation of the aircraft.

Problems solved by technology

The technical problem addressed in this patent is how to safely and efficiently guide aircraft through airports, particularly during surface operations, by providing accurate and easily understandable instructions to the pilot and ensuring that they follow them. The patent discusses the use of maps and electronic flight bags to display relevant information, as well as the importance of listening to the pilot's call sign for updates and modifications to the taxi clearance. However, the patent also highlights the limitations of current technologies such as heads-up displays and the need for more effective and affordable solutions.

Abstract

A system for multi-modal cockpit interface during surface operation of an aircraft comprises a head tracking device, a processing element, and a full-color head worn display. The processing element is configured to receive head position information from the head tracking device, to receive current location information of the aircraft, and to render a virtual airport scene corresponding to the head position information and the current aircraft location. The full-color head worn display is configured to receive the virtual airport scene from the processing element and to display the virtual airport scene. The current location information may be received from one of a global positioning system or an inertial navigation system.
